| Description: | Evince is a document viewer.
An array index error was found in the DeVice Independent (DVI) renderer's PK and VF font file parsers. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2640, CVE-2010-2641)
A heap-based buffer overflow flaw was found in the DVI renderer's AFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2642)
An integer overflow flaw was found in the DVI renderer's TFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince. (CVE-2010-2643)
Note: The above issues are not exploitable unless an attacker can trick the user into installing a malicious font file.
Red Hat would like to thank the Evince development team for reporting these issues. Upstream acknowledges Jon Larimer of IBM X-Force as the original reporter of these issues.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
